'The key le'v'ers'are preferably of different lengths,

Tlie key levers project, 'as' shown, tlir'ugl'slots 2l in the upper -frontv as indicated in Fig. '3. so that the. finger `pieces 25thereon may bc located far enough apai't'to be readily imniipulated. 'lhe 'segmental racks 21 aro' provided with. spur teeth arr'd'each is arranged to `enfngre tlle teetliiof'one of a pair of transmission spur'` gears 2Gund 2T. which 'arc mounted upon n shnt 281 One of 'the transmission fours of cach' pnir meshes with thc tcth of the corr'e'sponding!` rack 2l. while the other transmission gear 'of thc. pair meshes with the Y driven gear 16 on the corresponding disk 0f effect both additions and subtractions, and

will be-more fully. explained hereinafter. If additions alohe werefrequred, a single transmission gear -could be employed between each rack and the correspondin totalizer disk or, indeed, the racks [coul A directly engage the totalizer disks.

The racks 21 frsetting the totalizer disks are concentric with the shaft 23 whereon the controlling key levers 22 are mounted, so that the racks will properly mesh.withV the teethof the pinions 2t and 31 asthey are shiftedby thekey levers. The racks are held into engagement with the pinions of the totalizer by va universal .'b'ar'33 which. extends through segmental slots34 formed in the racks.` This universal bar also 'serves to. .Shift the/ 011 ,ot-.engagement the pinions, so that'fthe'keys and racks may be restored to normal position, without disturbing the totalizer and,',when the keys'` and racks are so restored, the'universal b ar is arranged to effect the rengagement.' of the racks with the totalizer. The universal bar 33 by its engagement with the slots 34 in the racks, engagement with the pinions of the totalizer as the racks are shifted by the keys. Tov move the racks into'and outof engagement with the totalizer, the universal bar is radially shiftable to and from theshaft 23. For this purpose the universal bar is fixedat its ends to a pair of radial arms 35, having enlarged inner ends with elongated openings 36 theein, through which the shaft 23 extends. These arms are varranged against the outer `fces of the pla-tesv 12, as shown, and the ends of the universal bar 33 which are connected to the arms 35 extend through openings 37 in the plates 12, which are of suflicieht size to permit the radial shift of the xuiiversal bar to'throw .the racks 21 into and out ofengagement with the 'pinions' of the totalizer, and the edges of these openings act to ide the movement of the universal bar 1n radial direction, but prevent itsmovement in any other direction. Springs 38 connected to the inner ends of the arms 35 and to pins 39 on the plates 12 tend to pull the universal bar inwardly and the racks 2l out' of engagement with A" The racks 2l properly holds the latter into are, however, normally h eld in engagement with the totalizer by a pair of cam arms 40 that are fixed to the ends of a shaft 41. This shaft is 'journaled, as shown, in the plates 12 below the shaft 23. The ends of the shaft extend through the plates and `carry the cam arms 40, whichengage cam lugs 42 upon the inner ends of the arms 35, and thus serve to normally hold the uni versal bar 33 in its outward position with the racks 2l meshing with the pinions of the totalizer and with the springs 38under tension. 'A Y As stated, the key levers 22 are journaled upon the shaft 23 and this shaft`-is preferably employed as a universal restoring member forreturning the key levers to initial position. For this purpose, the hub of each key lever providedwith a segmental slot 43 and .the shaft 23 is journaled in the plates -12 and is provided with a'seriesA of pins 444 which extend within the segmental slots 43. These of the Aslots 43, as shown in Fig. 1. When Any'of the-keys are 4shifted the shaft 23 will he rocked in the direction indicated by the arrow in Fig. l, by the engagement of the hubs of the key levers withA thepins 44 on the shaft. The slots 43 are, however, of

such length `that the several key levers 22 -may -be-Qmoved independently to variably" Vactua-te the, racks21, but by'rotating -the shaft 23 inreverse direction any of thekey levers whiclr have been shifted Tand the racks 21 connected thereto, will be restored to normal-or initial position.V` To thus rock the universal restoring'member orshaft 23 it is provided on one end '(as shown in Figs. 2 and 4) with a crank arm 45 which is pivot' ally .connected to one of a pair of. toggle links 46... The other toggle link 47 is pivoted to the plate 12 andthe joined ends of the toggle links carry an anti-friction roller 48, which isarranged to be engaged 'by a cam arm 49 on the end of the shaft 41.

When the finger keys 25 have been manipulated to operate the key levers 22 and racks 21 and thus operate the totalizer to add or subtract any sum therefrom, the shaft 23 is rotated in the direction of the arrows shown in Figs. -1 and 4` and the Yroller 48 on the toggle links 46 and 47 will be .moved to a greater or less extent toward the shaft 41. The shaft41 is then rotated through a cornplete revolution' in the direction of the arrow shown in Fig. 4 and the-cam arms 40 will first be disengaged from 'the lugs 42 on the arms 35, so that the. springs 38 may act to pins normally engage the pper ends loo shift the universal bar 33 inwardly and -disengage the racks 2-1 from the pinions of the totalizei'. T'he continued movement of the shaft will bring the cam arm 49 into engagement with the roller 4S and thus move the toggle links 46 and 47 to rock the shaft 23 and restore the key levers and racks 21 in circumferential Ydirection to normal. 'The cam arms 40 then rengage the lugs 42 and shift the universal ba.r33 back to its normall chine v.is then ready for the next operation.'

'In ord er that the diilerent numbers which -are added or subtracted may be printed, a'set of printing types are connected to-and rariahly operated by the v'key levers S22. Thesetypes are in the form of segments 50 andare each provided with aset o ftype 56 running from Oto `9. They are pivo'ta-lly connected to'the lower ends ofthe key levers 22 and are thus arranged inthe lower porvtion of the machine frame immediately above the paper or paper support,` u-p'on' between this extension `and a shoulder'53 on the corresponding key lever normally holds the segment into engagement-withl a projectiou or stop 54on the opposite side ofth'e lfey' lever. 'l

It should be printing types 50 andthe segmentalracks or drivers for the totalize'r are pi-votally coi1-v4 nected to the opposite ends of the 'printing` key levers and on opposite sides of the axis thereof, and that the printing types vand racks are concentric with the pivotal axis of the key levers, so'that the racks will prop- `erly` mesh with the pinions of the totalizer and so that the type on the print-ingftype s 'gments will be brought into proper relation with the surfaceof the paper or the like, upon which the impression is made.

Each type segment ,50 is provided'on its upper edge with a series of V-shaped notches' 55 which correspond in position with the type 56 on its lower face. These notches are arranged to coperate- `with the lower V-shaped or`beveled edge. 57 of a universal bar 58. This bar extends over the type segments 50 and its ends project through verti cal slots in the plates 12. Each end of the universal bar' 58 is engaged by the free end of a spring 60, which is fixed 'at its opposite end to pins 61 on the plate v 12. By this means tle universal bar is normally upheld within thevertical slots 59'.

When any number is to be added or subtracted the proper keys of different denominations will be operated to Ydiierent extents to set up the number. This operation of the key llevers will properly advance or retract thc totalizer and will variably shift the t ""e segments-50. The latter will be pressed "y1 edge 57.0f the universal barwith' the notches noted that 'the segmentalv 55 inf the upper edges of the type segments. The dies or type segments thus act as det-ent arms to hold the key levers in set position. After the number to be addedl or subtracted is vset up by the operation of the different denominational key levers, the shaft 4-1 will, as stated, be rotated through a complete revolution. This, as described, first disenages theracks 21 from the totalizer.' The l urther movement of-theshaft will bring the cam arms 40 into engagement with the universal bar 58 and'will depress thelatter against thetension of the springs 60 to .effect `the operation of thetype segments or dies 50, and 'thus impress the number' which .has been set up upon the paperbeneaththe machine. Thefurther movement of the shaft' 41 will move the varms-40 out of engagement with the universal bar 58 and, as previously described," will restore the key levers 22 'and racks 21 in circumferential ,direct-ion,f and at the same time will return the'type seg: ments orz di'esto their initial zero position. The'universal bar 33 and -racks21 are-then' restored to normal bythe cam "arms 4 0 ar1d' 90 the machine is ready for the next-operation.

'f The -shaft'dl could be rotated througha* .singlefrevolution at the end of-,ea'ch operationby hand, iff'desired. luther-preferred construction a*`s`pring'drum 62 is' employed.' .95 This drum is mounted upon astud shaft'63 that projects fromA one ofthe plates 12and is connected by` gears 64 and 65 tof-a'winding key 66. It is also connected b gears 67 and 68 to the shaft 41. Whent e, sp ring 100 mechanism is wound up it tends tof rotate. the shaft 41 "in the direction of the arrows indicated in Figs. -1 `and 4Q I The spring i Vmechanism 'isr however,v normally .held against operation byva rcleasable latch-69, 'which is pivoted to the" inner face of one of the plates 12, and is provided with a toothed upper end whichengages a notch'in a .disk- 70 xed to4 the' shaft' 41. The' lower end of the latch is connected to a push' rod 71 which -11o extends outwardly through the fro-nt wall of" the machine frame and is provided at lits outer end with la push button or key 72. A spring 73 coiled around the push ,-rcd 71 between the button 72 and frame, normally 115 holds the latch 68 inboengagemcntavith the notch of the disk 69, and the shaft 41 is thus held against movement. A slight'push b v 'the operator, howeverrupon the button 72 will release the latch, so that the spring 120 mechanism will rotate it. After a single revolution of the shaft the latch 68 will reengage the notch of the disk'69 and arrest.v the movement of the shaft.

The type segments 50, totalizer disks 14 125 and the controlling key levers 22 therefor are, of course, alike in numberand represent the different. denominations units, tens. hundreds, etc. These parts may vary in number in accordance with the size ofthe 189 .machine When any number 'is'to be added or subtracted it is first set up by promptly manipulating the finger keys25.l to advance or retract thevtotalizer thro; gh the niedium ofthe driving racks 21 and to shift the type 'segments-or dies 50 from'zeroV into position to print the number.- The parts wi1l.-be held- -in shifted position bythe engagement of the notches 55 on the type se ents with the loibeveled edge 57` of the universal bar 58.

Then by pressing thebutton 72, the operator will release thedisk 69 so that the'ca'ni sha-ft. 41 will-be rotated thro h a single revolu-' tion, and the-number which has been' set up will bev printed and the l parts .as

' previously described, to' zero'p'osition ready for `the next operation. -To facilitate. the

'setting up of the number by means of the tinger'keys-25-fthe front face `of the .casing adjacent the slots L24 is rovided with a -series of scales numbered rom .0 to 9.' 'As .keys are variably shifted it is diicult 110""readjat a .glance thenumber`set up on such a seriesof scales, and for this reason other indicating means are providedin connection with thefinger keys 'andcomprises a set of flat sprin 'strips 74, one of'which is connected'to eac 'key -lever 22 at its outer end and at a point inside and adjacent the wall `of the casing:...'l`hese. spring strips ex'- tend rearwardly om the upper ends-ot the key.

The numbers on the stri s are' visible through the slot 78 of the-cy inder and as the keysare depressed to -set up a number the corresponding springs will un coil and the number set up may be read at a.A glance throughY the slot or. a erture 78. Whenthe key levers are returne the spring strips will again coil up within the cylinf di'i'cal casing 7 5 To indicate the printing line of-'the inachine the laterally projecting Apointers .79 arer fixed to 4the lower edges of the outerend walls 1Q. The finger keys and the type segments are normally in zero .position-with the zeros on the type segments oppositel the printing line of the machine and imme-v diately below ,the universal bar 58, which, as described, is depressed to effect the impression ofthe type segments. In this way it' will be unnecessary to set up Azeros in'operating the machine, but it. is desirable that clearly shown in-Fig. 2.

the zeros to the left of the digit of highest denomination in the number shall notbe printed `and thatall zeros to the right of such shall be; printed.: To effect. this, the parts are.so arra edthat the universal ments .when in zero position. In the'form shown, 'the notches 55 in the type segments,

which correspond f to the` zero .position thereof, and which are .normally located beneatli the universal bar, are considerably deeper than the notches 55, so that'the limited shiftfof the vuniversal bar will beinsufiiciengto operate any .type segmenti that is zero position. vTo effect the printing. of all zeros to the right of the digitiof--highfA .est .denomination in the numbergeach 'ofthe type segments 50, except the one'of low'est` denomination, is provided :onv .one side and along its. upper. edge -xvith a laterally Vprobar 58 be inoperativeA upon the type seg-v -and all. zeros to theA right of the' highest e,- .number .will che ranged close together,as clearly` indicated Eig. 2,'A so that the n umbers may be coin# -pactly written. `The operating' key levers 22 and racks 21,..'however, requireimore rooin. F orthis reason the lowerendsof the outer key levers are bent inwardly, .as

' -The type segments or dies culd be inked with a roller, ifdesired, butpreferably, an

driver 21 for each of the totalizer disks 14' is prnided with two racks or sets of gear teeth 29 and 30. The rack teeth 30 mesh with a set of pinions 31 on a shaft 32, as described. These pinions are loose on the shaft and are held in' place thereon and are properl \v held apart by spacing sleeves 100 mounted on the. shaft between the gears or pinions 31. and by collars 101 fixed to the shaft 32 and engaging the outer faces' of the end pinions ofthe set. AEach set of gear teeth 29 is arranged to act as a-driver to rotate the correspondingr totalr/,er disk n l in one direction, while each 'set of gear teeth 510 and the pinion 31 engaged thereby is' arranged to art as a driver to rotate the cor-' responding tot-alizer disk in the'opp'site direction. pair of transmission gears 26 and 27 is interposed between each pair of drivers and the driven gear 1G of the corresponding totlizer disk.v yielding con-- nection is provided between 'each pair of transmission gears 26 and 27 and preferably comprises intel-meshing, crowned-toothed rateliets 102 upon the adjacent fac-es of the 7G tn'o'geais '2G and 27 of -each ]')air,`so that niotion' may be transmitted from one gear to the other whileeach (maybe rotated inde pendeiitly ofthe other. Thetfransmis's'ion earsfare shiftable back and forth in axial l irection and each is arranged to alternately engage with' the driven gear 16 of thecorre#A spending disk and with vone of the loppo- 'sitely acting drive gears therefor. To eff ect thea-xial'shift of thepairs of transmisision gears, and to' hold the ratchet teeth in' ieldingngagenient', these gearsare loosely vmounted up'on the 28which extends' '-tliiough the plates 12 and 10 and is 'aially 'shiftable to al'ir'nitedf extent; *Buttons 103 pon the ends of this shaft'A are employed or convenience in shifting it backend forth, and also act as stops to engage the end-walls or'plates. 10 and vlimit the movement ofthe shaft. The shaft' '2'8- held oneoi` the Oth'er of itsv two positions by a' d og 10i (scc .-Fig. 4),` which: `1s"}:i'vo ted intermediate its- -ends to on'e of the sideplates 12and is prof vided with a beveled end`A arranged to engage vne of a pair of V-shaped, a-nnularfgrooves 105 formed in the shaft. sprin? 100, conncted to the opposite end of ,t ie dog or latch and to a -.pin n the'plte. 12, yieldingly presses the freez'beveled .end of the-A dog or latch into engagement' -with .one of Slob the notches.l 105 inr the shaft.

' disk is shifted by the transfer devices, andv -the ratchet teeth intermediate the pair of' transmission gears 27 engage thev drive pinions 31 and the gears 26 engage the driven gears 16 on the totalizer disks. In Fig. 8, the gears 27 ,engage the driven gears 16, while the gears 26 mesh Vwith the rack teeth 29 of the driving racks. The driving racks .21,are shifted by thelinger keys in. the dilrection indicated bythe arrows in Figs.l 7 and l8. When thevparts are in the 'positionsliown in Fig. 7,- the rack teeth 30 will rotate the pinions 31, the latter will rotate the transmission gears 27 and these gears will drive the totali'zer disks through the medium of the ratchet teeth 102, transmission gears 26 and gearsl'. -Whenjthe parts areA in the position shown in- Fig.' 8,. the-'rack teeth 29 will rotate the gears 26v and the latter will drive the totalizer disks in the op.'-

posite-direction through themedium of-.the4

ratchet teeth 102`,'transi1'iissionv gearsf27 and driven gears 16.- In onef'position of thev transmission gears, the numbers set up: byl the finger keys will be. added tothe totalizer,"

while in the other position they willbe subtracted therefrom. Preferably', the totalizei" disks are so numbered-that whegpthe transmission' gears are in thefpositi'n shown in Fig. 8, the totalizer/ disks will be rotated in forward dirgction-lthat is to say` thenum' Vgears 26 and 27 of a pair isin engagement withhthe lgear 16 of the corresponding t0- talizer disk, it will move'independentlyof the other gear of the pair when its totalizer transmission gears will slip past each other.

501 As show n, the transmission gears 26 'and 27 and the ratchets .102'ea ch have ten teeth, while the gears 16 have 'twenty teeth` so that the moiement of any of the totalizer disks through oiie step or through one-.tenth of a revolution, will require the rotation of the transmission gear in mesh therewith through one-fifth of a revolution or through .the space occupied by two teeth.v When the enable the transmission gears 26 to properly rotatev thetotalizer disks through the medium of the transmission gears 27 and A,driven gears 16, while the inclined, faces of the ratchet teeth will permit the independent lmovement in thesame direction of the totalizer disks, gears `16 andv transfer gears 27. When any of the totalizer disks are adl'vanced by the transfer devices, the teeth of two intermeshing ratchets 102 ride over one another and thetransmission gears shift slightly along theV shaft 28. This yielding shift is permitted by the spring 109,' which.;

AThe one-way, yielding connection be tween the pair of transmission gears permits the shift of the totalizer disk the traiisfer devices independentl `of the drivers therefor. `-It should also e noted that the operation of the finger keys, driving racks and printing dies or segments 50f-is conios trolled by three universal members, that is to san the bar 33 is a universal member for shifting the drivers into and out of engagement with the totalizer, the bar 5S is va imiversal member for holding t-lie printing dies in set position and for effecting the iinpression thereof,"and the'shaft 23 is a universal member for returning the key levers, dies and racks to initial position. These thi-ec universal members are preferably controlled. asdescribed, by a single means consisting of the shaft 41, and cam arms thereon, and this controlling means, as stated, is preferably actuated by a spring mechanism that is provided with a releasable latchv for normally holding it against operation.

The improved machine may be conveni-V ently employed for printing lines of figures 'upon Sales sheets or books= and for adding or subtracting the same. Iii the form shown, the device. may be readily shifted about and placed upon the paper wherever it is desiredto print lines of numbers. If desired, the machine couldl be mounted upon guide rails and shifted over a stationary platen upon which the paper or book is held, or-tlie machine itself could be Stationary and the paper mounted :upon a platen arranged'to move be.- ncathnthe.machine.. By arranging the machine either for adding or subtracting, it is especially adapted fer use in making out bills or statements of account. Tliefdebits can be Jreadily added and vthe credits sub-- tracted, sothat`v the balance due may be readily ascertained. By shiftino' the ribbon the debits may be printed in blaack orblue ink and the credits in red ink, as is theeoni-v 'A mon practice.' -Vhen avcomputation is 'com leted, the total or result shown bythe totalizerv-'ill beset up on the finger keys and printed.
